Pennsylvania State Police are looking for a blue Ford or Mercury sedan that allegedly cut off another car on Interstate 78, causing it to crash.

At 7:40 this morning, the car merged from the ramp into the center lane of Interstate 78 westbound in South Whitehall Township, police said.

Amber L. Feist, 28, of Allentown, lost control of her 2000 Daewoo as she tried to avoid crashing into the other car and it spun out in a counter clockwise direction, police said.

Feist's car traveled across the left lane and the passenger side of the car struck the center concrete median before traveling back across the highway's center lane, police said. The car stopped facing in the southwest direction of 78's center lane. Feist was not injured.

The car that was merging did not stop, but a witness was able to describe it to police.
